LOUISVILLE, Ky. (AP) — A man who pleaded guilty in the 1994 slaying of a University of Kentucky football player has been seriously injured in an auto accident, authorities said Sunday.

The Courier-Journal of Louisville reports (http://cjky.it/UD3reB ) that Shane Ragland was hurt Saturday afternoon in an accident that shut down part of the Snyder Freeway. Louisville police say Ragland was traveling on a freeway ramp to eastbound Interstate 64 when he lost control of his Dodge Durango and it struck a guardrail.

Louisville police spokeswoman Alicia Smiley said Ragland was ejected and the Durango came to rest on its roof. He wasn't wearing a seatbelt.

Police said Ragland was taken to University Hospital and was in serious condition Sunday. No drugs or alcohol are suspected in the crash.

A jury convicted Ragland of murder and sentenced him to 30 years in prison in the shooting death of football player Trent DiGiuro, but his conviction was thrown out in 2002 after it was learned that an FBI analyst lied during a pretrial conference. Prosecutors had argued Ragland shot DiGiuro because he thought the player was responsible for blackballing him from a UK fraternity.

Ragland later pleaded guilty to second-degree manslaughter and was sentenced to time served plus three days. In a civil wrongful-death case, he was ordered to pay $63.4 million to DiGiuro's family.
